You're doing fine, but you might want to consider 0.70 just in case
there were some bug fixes recently.

Aha.  It appears that your system needs extra libraries to make socket
code work.  Good thing you looked in the log file.  I vaguely remember
having to add "-lsocket" to make such code compile on suns, for
instance.

You might try:

    LIBS=-lsocket ./configure ...

or

    LIBS="-lsocket -lnsl" ./configure ...

and see if that will convince the configure script to link with the
appropriate system libraries.  You will likely have to edit the Makefile
which is generated by this to do the same thing when it goes to build
mpiexec.

I'll work on a proper patch for you next week.
